Mercedes faced immense criticism when it abandoned the "M177" engine for the latest AMG C63. Despite rumors of an eight-cylinder return, the sports sedan is not reverting to V-8 power. However, a newly developed, large-displacement combustion engine is in the works for a late 2027 release. It’s a "next-generation, high-tech electrified V-8" intended for performance models based on the AMG.EA platform.
